【摘要】：目前,我国正处在高速发展阶段。在工业、农业、电子等科技飞速发展的带动下,经济条件得到长足的进步,人民生活水平不断提高。但是,在发展的同时,很多负面问题在逐步显现。生活在一、二线城市的公民收入增加、积蓄逐渐变的丰厚,很多人开始拥有私人机动车。看似进步的局面却埋藏了巨大的隐患——越来越多的机动车几乎占据了城市的主要地面交通资源,城市地面交通配套设施建设速度远不及飞速增长的汽车数量,地面交通变的拥堵不堪。于是,很多城市将发展城市轨道交通作为城市公众设施建设的最重要目标之一。从1868年伦敦建成第一条地下铁道以来,到现在世界上已有36个国家和地区的78个城市修建了地下铁道,总运营线路长达5500km。建成的线路均包含专用通信系统,大多数也包含民用通信系统。其中专用通信系统用于轨道交通车辆调度、安排及轨道交通运营公司工作使用。而民用通信则是为乘车的旅客所建设,让市民能够在乘车过程中方便的进行通信(尤其是地下轨道交通)。本文所讨论的MSTP传输系统主要针对专用通信系统,而民用的系统则可根据当前电信运营商的主流技术方式进行构建。本文将从SDH体系知识、数据通信MPLS VPN知识及RPR弹性分组网络知识进行入手,开展学习及深入研究系统基础知识。掌握系统所需的知识基础上,对轨道交通通信网络的组成、构建方式进行分析,并对通信系统的各上层子系统从需求的承载模式、承载带宽及承载端口数量几个方面进行详细的系统分析、需求提取及需求汇总。掌握知识和需求后,通过参与建设工程,对整个使用MSTP技术的轨道交通通信传输系统进行链路分析及使用规划、网络构建、保护方式选择、设备硬件配置规划、基于需求分析的业务端口规划及时隙规划。通过上述所有设计及规划工作,做出整个系统的实施规划,并通过设计规划指引,对网络进行参数设置。最后,验证通过配置的MSTP传输网络设备是否能够按照规划设计,对所有上层系统进行稳定、高效的业务承载。经过上述的学习、分析、规划、设计及实施,将整个学习、研究及实践进行记录和总结,形成整套技术方案并形成本论文。本文还将对未来的技术发展进行展望。分析MSTP技术进行承载网优点及弊端。将其优点进行发扬,对其弊端分析产生原因,并采取技术手段进行规避。同时,文章将对新兴技术方式是否能够适用于当前的建设模式进行分析。从当前使用的主流技术中总结技术经验,从新技术中掌握新思维,为不断升级的技术环境积累知识,当技术环境满足新技术使用时,可将新技术立刻应用并解决建设需求。学生通过撰写论文将全面掌握MSTP技术在轨道交通通信系统中的应用,拥有从需求分析、构建规划、系统设计、系统实施等几方面全面负责系统的技术管理能力。
[Abstract]:At present, China is at the stage of rapid development. With the rapid development of science and technology such as industry, agriculture and electronics, the economic conditions have been made great progress and the people's living standard is constantly improving. However, at the same time, many negative problems are gradually appearing. The income of citizens living in the first, two line cities is increasing, and the savings have gradually become rich and rich. Many people begin to own private motor vehicles. The seemingly progressive situation has hidden a huge hidden danger - more and more motor vehicles almost occupy the main ground traffic resources in the city. The speed of urban ground transportation facilities is far less than the number of rapidly growing cars, and the ground traffic is congested. So many cities will develop. Urban rail transit is one of the most important targets in the construction of urban public facilities. Since the first underground railway was built in London in 1868, there have been 78 cities in 36 countries and regions in the world to build underground railways. The lines in which the total operating lines have been built up to 5500km. contain special communication systems, and most of them include civilian use. The special communication system is used for the rail traffic vehicle scheduling, the arrangement and the operation of the rail traffic operation company. And the civil communication is built for the passenger, so that the citizens can communicate easily during the ride process (especially the underground rail transit). The MSTP transmission system discussed in this paper is mainly aimed at the special purpose. The communication system, and the civil system can be built according to the mainstream technology of the current telecom operators. This paper will start with the knowledge of SDH system, data communication MPLS VPN and RPR elastic packet network, and carry out the study and study the basic knowledge of the system. The composition and construction mode of the network are analyzed, and a detailed systematic analysis is made for the upper subsystem of the communication system from the requirement bearing mode, the load bandwidth and the number of carrying ports, and the requirement extraction and the demand summary. After mastering the knowledge and demand, through the construction project, the whole MSTP technology is used for the rail transit. The system carries out link analysis and use planning, network construction, protection mode selection, equipment hardware configuration planning, business port planning and time slot planning based on demand analysis. Through all of the design and planning work mentioned above, the implementation plan of the whole system is made, and the network parameters are set through the design planning guidelines. Finally, the network parameters are set up. Verify that the configured MSTP transmission network devices can be designed and designed to stabilize all the upper systems and carry high efficient services. Through the aforementioned learning, analysis, planning, design and implementation, the whole learning, research and practice are recorded and summarized, form a complete set of technical schemes and form a cost paper. This article will also be the future. Analyze the advantages and disadvantages of MSTP technology, carry forward its advantages, analyze its disadvantages, and adopt technical means to avoid it. At the same time, the article will analyze whether the new technology can apply to the current construction mode. By mastering new thinking in the new technology, accumulating knowledge from the new technology environment, when the technology environment meets the new technology, the new technology can be applied immediately and the construction needs can be solved. By writing the paper, the students will master the application of MSTP technology in the communication system of the rail transportation, and have the requirement analysis and the construction plan. System design, system implementation and other aspects are fully responsible for the technical management capability of the system.
